Entrez Gene Summary for CLRN1 Gene

  • This gene encodes a protein that contains a cytosolic N-terminus, multiple helical transmembrane domains, and an endoplasmic reticulum membrane retention signal, TKGH, in the C-terminus. The encoded protein may be important in development and homeostasis of the inner ear and retina. Mutations within this gene have been associated with Usher syndrome type IIIa. Multiple transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

Disorders for CLRN1 Gene

(2) OMIM Diseases for CLRN1 Gene (606397)


  • Usher syndrome 3A (USH3A) [MIM:276902]: USH is a genetically heterogeneous condition characterized by the association of retinitis pigmentosa with sensorineural deafness. Age at onset and differences in auditory and vestibular function distinguish Usher syndrome type 1 (USH1), Usher syndrome type 2 (USH2) and Usher syndrome type 3 (USH3). USH3 is characterized by postlingual, progressive hearing loss, variable vestibular dysfunction, and onset of retinitis pigmentosa symptoms, including nyctalopia, constriction of the visual fields, and loss of central visual acuity, usually by the second decade of life. {ECO:0000269 PubMed:11524702, ECO:0000269 PubMed:12080385, ECO:0000269 PubMed:12145752, ECO:0000269 PubMed:15521980, ECO:0000269 PubMed:18273898, ECO:0000269 PubMed:23304067}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Retinitis pigmentosa 61 (RP61) [MIM:614180]: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. {ECO:0000269 PubMed:21310491}. Note=The disease is caused by mutations affecting the gene represented in this entry.
